Illinois Application July 1, 1948, `Serial No. 36,5118

, 6 Claims. 1

More particularly the invention relates to an end stop for tubulartracks and which is adapted for use with different types of supportingbrackets.

It is the general object of the invention to from the following detaileddescription taken in connection with the accompanying drawings wherein:

Fig. 1 is a fragmentary side elevation of a tubular track together withits supporting bracket and a preferred form of the invention associatedtherewith;

Fig. 2 is a section taken approximately along the line 2 2 of Fig. 1;

Fig. 3 is a section along the line 3--3 of Fig. 1;

Fig. 4 is a perspective view of the preferred form of the invention;

Fig. 5 is a fragmentary elevational view of the preferred form of theinvention associated with a barn door track having an apron along thehanger slot;

Fig. 6 is a section along the line 6 6 of Fig. 5.

While I have shown in the drawing and will hereinafter describe indetail a preferred embodiment of the invention, it is to be understoodthat various modifications may occur to those skilled in the art Withoutdeparting from the spirit and scope of the appended claims.

As shown in Figs. 1 to 3, a tubular track section l Il is supported atone end thereof by a bracket II. The bracket comprises an angle memberI2 and a ribbed tubular member I3 the central rib of which provides anannular pocket, the angle member being suitable for attachment to a Wallor the like by means of a vertical leg thereof. The tubular member hasan internal diameter permitting the track to pass therethrough with asnug t and has a slot I4 coinsiding with the slot I5 in the track. Tosecure the track section against rotation and endwise movement in thebracket I! the track section is provided with an end slot I6 adapted tointerengage with a lug I'l which projects inwardly from the tubularmember I3.

An end stop I 8 is herein shown inserted in the tubular member I3 of thebracket and with a (Cl. 1li- 94) 2 portion thereof extending between thetubular member I3 'and the end of the track as shown in Fig. 2. The endstop I8 as shown is a member formed from a strip of sheet metal and isgenerally U-shaped, having an end portion' I9 and a pair of 'curved legportions 2l). The end portion I9 isy preferably flat as shown. The poretions 2li are curved on a 'radius to lcorrespond with.y the curvature ofthe tubular track section I0 and its supporting bracket II. Adjacent.the end portion I9 the leg portions 2!) are offset outwardly at 2I sothat the parts thereof imme-` diately adjacent the end are of a'reduceddiameter itting Within the end portionA I 3 of the ribbed tubular memberI3. This construction permits the end stop to be` snapped into place inthe supporting bracketby pressing-the leg 4portions 28 toward eachother' as they are in-f serted into `the end of the tubular member I3.As the end stop reaches the position shown in Fig. 2 the leg portions"expandinto the pocket formed by the'rib portion of thev member I3 asshown and permitfthe entry-of the'track section Ill and the interlockingthereof with the lug I'I. Preferably, the leg portions 20 aresufliciently long so that the free ends thereof reach the reducedportions I3 at the other side of the rib of the tubular member I 3 andthereby clamp the end stop against endWise movement.

As shown in Figs. 5 and 6, the end stop I8 is used in connection with atubular track section 22 of the type having a. hanger slot 23 and adepending apron 24. This track section is supported by means of abracket 25 which is secured thereto as by rivets 26 in a well-knownmanner. rlhis form of track is also adapted for mounting on a verticalwall such as 2l and is herein shown as secured thereto by attachingdevice 28.

The end stop I8 may readily be secured to the track 22 as shown in Figs.5 and 6 by slipping the leg portions 20 over the end of the tubulartrack section and then securing the end stop to the track section bymeans of a spike 29 which passes through coinciding apertures 30 and 3|in the end stop and track section and into the wall 21.

The end stop in the form herein illustrated is of extremely simpleconstruction and includes portions 'Ztl which are suiciently resilientto per- .mit it to be snapped into place when used with a supportingbracket of the type indicated at II. It may also be used Withoutalteration in connection with the form of track illustrated in Figs. 5and 6. The advantage of an end stop adapted comprising a U-shaped sheetmetal member having an end portion and a pair of leg portions shaped toconform substantially with the surface of the tubular track, said legportions being bent outwardly a short distance from the end plate so asto interengage in a ribbed track supporting bracket.

2. An end stop for tubular tracks having a ribbed track supportingbracket comprising :a

plate and a pair of leg portions shaped to conform substantially withthe surface of the tubular track, said leg portions being ioisetoutwardly a short distance from the end plate so e as to interengage insaid ribbed track supporting bracket.

- 3. In combination, a tubular barn door track, -a

` bracket for said track having a supporting angle member adapted forattachment to a barn wall and a tubular track receiving member having aportion gripping said track and a portion providing an annular pocketpartially surrounding the portion of the track adjacent the end thereof=and extending beyond said end, and a lU-shaped sheet metal end stophaving outwardly .r 3:0

oiset legs which are engaged within said pocket and which extend oversaid portion of the track so as to be locked Within said pocket by saidportion of the track.

4. In combination, a tubular barn door track, i

a bracket for said track having a supporting angle member adapted forattachment toa barn wall and a tubular track receiving member having aportion' gripping said track and a portion providing an annular pocketpartially surrounding the portion Vof the tract adjacent the endthereofand extending beyondsaid end, and a sheet metal end stop having apair Iof resilient leg portions shaped to conform substantially withU-shaped sheet metal member having `an end j 4 the tubular track, havingoutwardly oset sections which are snapped into the annular pocket in thebracket and extend over said portion of the track so as to be lockedwithin said pocket by said portion of the track and so as to be lockedagainst endwise motion by the margins of the pocket. f

5. A combination of elements for use with a tubular barn door track,comprising, a. supporting bracket for the track having a ribbed portionforming a circumferential pocket, and a U-shaped sheet metal memberhaving an end plate and a pair of leg portions shaped to conformsubstantially with the tubular track, said leg portions 'short distancefrom the end of the plate and having said sections which are offsetfrictionally engaged Within the pocket formed by the ribbed portion ofsaid bracket.

6. A combination of relements for use with a tubular barn door track,comprising, a supporting bracket for the track having a ribbed portionforming a circumferential pocket, and a sheet metal member having :anend plate and a pair of resilient leg portions shaped to conformsubstantially With the tubular track, said leg portions having outwardlyoset sections a short distance from the end of the plate and having saidoiset sections snapped into the pocket formed by the ribbed portion ofthe bracket so that the resilience of said leg portions resistsdisplacement of said member from said bracket.
